Abstract
A method of recording signals on a magnetic medium, in which a first magnetic head (1) blanks a wide track by recording signals at a first azimuth angle and a second magnetic head (2) records a narrower signal track (15) by recording signals at a second, differing azimuth angle. This permits feeding the same current or signal through the head windings (8,9) of both heads, thereby economizing on driving circuitry (10). Due to the differing azimuth angles, the reading head does not pick up any significant amount of noise from the border regions defined between the edges of the signal track and the wider blanking track. The width of the signal track and the widths of the border regions sum to equal the width of the blanking track.
